Allsång på Skansen is a Swedish tv show held at Skansen, Stockholm, every summer on Tuesdays. The audience is supposed to sing-along with musical guests to well-known Swedish songs. The show started in 1935 on a small scale - about fifty people in the audience. Today about 10 000–25 500 people come to each performance.

The four friends, Leo, Iggy, Sam and Alex, transform overnight into a successful boy band. But what happens to their friendship when they get their dreams fulfilled and celebrity puts their relationships to the test?

Adam and Bianca meet at a music camp the summer before year seven. Back in everyday life, they keep in touch every day through their mobile phones. Do they become each other's best friends, or are they perhaps more than friends? Together, Adam and Bianca create covers of songs they love.
